Thank you for your question. I will try to speak in French.
The Iranian nuclear program was interrupted by the revolution in 1979, but it was decided to reinstate the program in 1984. At that time, the President of Iran was Mr. Khamenei, who is today the supreme leader of Iran. The Prime Minister, an institutional position that no longer exists today, was Mr. Mir-Hossein Moussavi. The program continued after the end of Mr. Khamenei's presidential term, under Mr. Khamenei's authority as supreme leader, during the presidency of Mr. Rafsanjani, considered a pragmatic conservative. Mr. Rafsanjani stepped down in 1997, and his successor was Mr. Khatami, a reformer who talked about a dialogue of civilizations with the world, but who was secretly building a nuclear bomb in Iran, as was discovered in 2002 and brought to light by the American secret service.
The reformer was replaced by Mr. Ahmadinejad. Mr. Khamenei, who was President in 1984, remained as the supreme leader. Mr. Ahmadinejad pursued the same nuclear policy. This means that concerning the nuclear issue, at least, there is no difference between the reformers, the conservatives, the radicals, the pragmatics, the supreme leaders and the officials elected by the people. This political stance taken by the Islamic Republic of Iran has remained the same for nearly 25 years.
There may be stylistic changes on this issue, but I cannot imagine the supreme leader of Iran deciding to abandon the nuclear program, unless he is forced to make a choice. He must choose between the bomb, a nuclear arsenal and political aspirations, which such an instrument of power can help Iran materialize or pursue, and the survival of the regime.
I believe that the policies of the western world, the international community and the free world on discussions around the nuclear question must force the supreme leader of Iran to make this choice. We must realize that as concerns the nuclear issue and the loyalty of the men who are in a position of power in Iran, throughout the history of revolutionary Iran, devotion to the ideals of the revolution, to its survival and that of the Islamic regime, is a political constant of all the men who have shared power and participated in the government administration of the Islamic Republic.
We can always hope for a change in the style of governance. It is true that there have been men, such as Mr. Larijani, who were much more agreeable, sophisticated, educated and polite in their conversations with the free world.
However, Iran's behaviour towards minorities, women, religious minorities and its neighbours, as well as its attempts to assassinate exiled dissidents in many countries, including countries that are friends of Iran, for example, in Europe, have always been the same throughout its history, regardless of the type of politicians and leaders in power.
You must understand that the changes will be cosmetic. They will primarily reflect the strategy of the supreme leader towards the international community and indicate his commitment to changing the direction of the regime around the nuclear issue and around the other questions that concern us today.
